🦋 Hormone Spotlight: Thyroid Hormones (Your Body’s Metabolism Manager) 🦋
Your thyroid is a small gland with a big job. Thyroid hormones help regulate how your body uses energy and affect nearly every system in your body. When thyroid levels are off, you can feel “not like yourself” even if labs are told to be normal.
The key thyroid hormones include:
• T4 (Thyroxine) – the storage hormone
• T3 (Triiodothyronine) – the active hormone your body actually uses
• TSH – the signal from your brain telling your thyroid how hard to work
Thyroid hormones help support:
• 🔥 Metabolism and weight regulation
• ⚡ Energy levels and endurance
• 🧠 Brain function and mental clarity
• ❤️ Heart rate and circulation
• 😴 Temperature control and sleep
• 💇 Hair, skin, and nail health
• 😊 Mood and emotional balance
When thyroid hormones are too low or out of balance, people may experience fatigue, weight gain, brain fog, hair thinning, feeling cold, mood changes, and slowed metabolism.
Thyroid health isn’t just about one number. It’s about how all thyroid markers work together and how you feel.
